My personal snapping point as a consumer occurred several years ago, over something that's definitely not anecdotal: When Amazon employees are frisked at the end of their shift (which is a practice that applies to at least some warehouses), they are not paid for the time they spend waiting in line to be frisked. This is not an anecdote; indeed Amazon fought and won a court case insisting that it has the right to not…
And they felt so strongly about this they appealed a case all the way to the Supreme Court... That was the snapping point for me too and I have not ordered from them in a long time.
